The male part of a flower that produces and stores pollen is called the anther.

Here's a breakdown:

* Anther: The anther is the top part of the stamen, the male reproductive organ of a flower. It is typically a sac-like structure that contains pollen grains.

* Pollen: Pollen is a fine powder containing the male gametes (sperm) of a flower.

* Stamen: The stamen is the entire male reproductive structure, consisting of the anther and the filament (a stalk that supports the anther).

The anther plays a crucial role in plant reproduction. When pollen is released from the anther, it can be carried by wind, insects, or other pollinators to the female part of the flower (the stigma), enabling fertilization and the formation of seeds.
